Drive Select and Dynamic Nuance
My understanding is that each time you start the engine fresh, the actual setting of the Engine/Trans is Comfort, even if the Drive Select mode (i.e. what the dash displays) says Dynamic. This is supposedly for gas mileage / EPA / similar reasons.
To actually get the car to go into Dynamic, you can cycle through the modes by clicking Drive Select enough times to cycle back around to Dynamic again, or you can hit the button once and use the main MMI scroll wheel to select Dynamic again.
Example: You are in Dynamic, driving around in "S", etc. and you stop, shift to Park, and turn the car off. You then restart the engine, and shift to Drive, and the display still shows "Dynamic" but now shows "D" (not "S") because the car restarted with the Engine/Trans mode in Comfort due to its programming. If you then re-select Dynamic via Drive Select, you'll see the display immediately switch to "S" (and still "Dynamic"), the idle revs raise slightly, etc. Hopefully all of that was clear so far.
My question is, at the point when you restarted in "Dynamic" and switched to Drive, but have NOT yet re-selected Dynamic via Drive Select —*and thus the Engine/Trans is in Comfort still —*will pulling the shift lever back to engage "S" mode have the complete same effect as re-selecting Dynamic as described above? Or... does it go back to Comfort setting after pulling the lever again to go back to D, and thus you still have to ultimately re-select Dynamic via Drive Select to get full, true Dynamic?
My goal is to be able to start the car, drive in "D" for the first several minutes until the engine/oil/trans/etc. are thoroughly warm, and then engage true Dynamic and "S" by pulling the lever back, without having to use the Drive Select button to re-enable Dynamic after starting the car up.
Will pulling the lever achieve that, or do I still need to select Dynamic to get it to truly engage Dynamic mode? I know the trans will definitely be in "S" ("Dynamic") when pulling the lever back, but will the engine mode also be in Dynamic? Given that the setting option in Individual mode lists it as "Engine/Trans" (suggesting they're not separable), I would suspect/hope that pulling the lever back truly re-engages Dynamic for both engine and trans, just as re-selecting Dynamic via Drive Select does following a restart, but I'm not sure how to tell for certain, so I'm hoping folks familiar with the underlying programming may be able to provide insight.
As additional context, before I installed a CETE valve controller, I would have to re-select Dynamic just to get the valves to open. The CETE eliminated that need (plus other benefits!). However, I'm wondering if I still need to re-select Dynamic to actually get Dynamic in terms of engine performance, or if pulling the lever when already in "Dynamic" will achieve the same result.
